To all whom it may concern: -v 1 Be it known that I, Louis ScHULzE, of Louisville,

have invented a new and useful Improvements in Beerin the county of Jefferson, and State of Kentucky,A

Coolers; and I do hereby declare the following to be Figure 2 is a longitudinal vertical section of rthe main part; and

Figure 3 a vertical cross-section of the same. Like letters of reference indicate like parts in the severaliigures. y The principal requirement of a beer-cooler is to give the broadest possible` surface for the beer to pass over,

to allow it tospread, with thesmallest possible depth of the pipe through which the water flows in the opposite direction to the beer, so as to quickly pass the Vwater throughthe pipes, and keep up a rapid circula# tion, for the quicker the circulation4 the cooling-effect.

In beer-coolers as now oonstructed-the pipesare all greater is the rounded, which,I necessitates that the beer in the, longitudinal centre of the pipe through which it runs, and where it is deeper than at lthe sides, does not cool oil as quick as at the sides, and consequently the whole mass of the beer is not only unevenly cooled, but parts ofhe beer are never exposed to the influences of the co Again, in beer-coolers in which the beer is run through pipes, with water running in opposite .direction below it, the pipes incrustate very quickly with the impurities of the water, and vthe pipes soon are either stopped up or eaten away by the salts forming on them, by reason of their no t being cleansed, which, with their present construction, is impossible.

A ir has been applied to assist in cooling the beer when water is used; hut the blast has always been a one-sided one; that is to say, it either strikes the beer in the direction of itsl flow, and consequently only touches its surface, or itv strikes the beer against its ilow,and spattcrs it all over.

I obviateall these difficulties by my improved apparatos, by means of which Iv can cool beer, in summertime, to such a degree that itcan be at once used.

I have cooled beer with my apparatus in the latter part of August, down to 30, or almost thedegree of cold of ice-water, which is' more than required, 42 being all that is needed, so that I need not manufacture my beer for summer-use in winter, and store it up, but make it in summer as well as in cold weather, and, passing; it through my improved cooler',

ender it t at once for use.

And the nature of my invention consists ln-- i First, the construction of the channelsrthrough which the beer -runs irnone direction, and the water in. the opposite one, with square bottom and sides, so 1 that the beer spread over the surface of the channel, 'and an equal surface of water touches the under side of the channel in such a manner that then stream of beer is of equal thickness, and is exposed all the way, until it is discharged, .to an equal surface of equal thickness of the cooling-liquid.

Second, the mode of -tbrming -the water-channel open vat both ends,- and making it continuous by means of a peculiar packing, hereinafter described, so that easy access can be had'to the same for ,the purpose Lof cleans ing it.

Third, the application, for' coolingl the beer asit runs `down the channels, inaddition to the water, of contents of atmospheric air, passed over ice by afan, or equiva `nt means, said currents striking the beer at vertical right angles, permeating, stirring, and turning it at the same time.

Fourth, the construction and application of stirring and 'turning-devices, by means of which thebeer is f tlu'ued and stirred so that all its particles come in contact with the cooling-surface.

Fifth, the construction of different parts of the apparatns, as hereinafter more fully described. i A A A A', in the drawings, represent four standards or posts, secured to each other by means of bars c c. Between these parts are secured, in any suitable manner, inclined in opposite directions to each other,

the pipes or channels B, each one having a double bottom, b, thus forming two separate channels, b and c, the former serving or the hot beer to be cooled, and the latter for the water. v

The channels B are constructed with square sides and bottom, and are connected to each other, at their ends, by means of end-plates d and by side-'plates e, which latter form a continuation of the channels b in such a'manner that the beer runs from the top chan-` nel to the lowest channel into the discharge-vat in one continuous stream. The ends of the water-channels c of each contiguous pair of channels, lB, are thus left open, as shown in the two upper channels, B, iig. 1,

the packing which forms their continuation being removed.

A flange, j, is formed on the contiguous ends of channels B, against which is placed a vwooden packing or plate, g, which is held in place by two iron frames,

' h h', secured to each other by screw-bolts and' nuts i', as shown, the frames h being formed in two pieces,A

and placed in the rear of ilangesf. Thus, when thev ,packing is removed, easy access is had to thewaterchannelscl for the purpose of cleaning or repairing.

U is a pipe, connecting with -the vats from which 'the beer is run into the channels b.

The upper and lower ends of channels' c terminate in pipes ortubesc andes, the former serving for a discharge-pipe of the water, and -the latter to ,be attached to a. force-pump, or a strong head of water, higher than the apparatus, to force water through the channel o1. y

The lower end of channel b' terminates in a receivingvat or receptacle, D, from which the beer may be run of into barrels, or otherwise disposed of for use.

In suitable bearings, on the sides of the two upper channels, b', 'are pivoted rollerslj, provided with paddles k, which latter just clear the bottom of b when the. shas areturned. These rollers and paddles are moved by the beer as it runs down 4these channels, and by them the beer is -turned and stirred several times, so as to 'expose Vall its parts to the coolingsurface before itruns into the lowertchannels.

`Over the lthree lower channels, b', secured inany suitable manner, are suspended pipes E, closed at one end, and connectedfatxthe other, by meansof ilexible tubes F,to the mouth `of a blower or fan, G, which is situated lover an ice-box or receptacle H, having a perforated bottom. The fan is provided with paddles J ,1 and is provided with a cover. Thh under side of pipes E is perforated, as shown at n', and the pipes run parallel with their respective channels b.

l The operation of the apparatus is as follows.

Water is forced into the channel o' bya force-pump or any other suitable means. The beeristhen allowed l to runv into the channelv b', passing from end to end, the

water runningin opposite directions.` As the latter passes' pipe to pipe, or `channel to channel, it touches, on-the inside,1the plates d, which, not coming in contact with the hot beer, are always comparatively cool; and on the outside vit comes in contact with the wooden packing g, which, being a non-conductor of heat, imparts no heat to the water, though it touches the ends of the channels b'. Thus, the -water mounting from channel to channel, loses none of its coolingpower during the interval in which it does not touch the double bottom b.

The channels b cl being square in shape, the beer i andthe water always are each of equal depth or thick- .ness in the entire channel, and thus each part of the beer is exposed to equal cooling-surface of water:

The paddles k are moved by the beer as it vruns down channel b', and stir and turnthe beer, so that everypaiticle of it is exposed to the cooling-surface through the last three channels b', it is exposed to currents of cold air, drawn up through the ice-box H,

of fan G. These icecold currents of air striking the current of beer at right angles, 'thoroughly permeate it, and stir it powerfully, so that each particle of the beer comes in contact with the cold air. By this means, the beer, when it anives at the receiving-vat D. is noi. only perfectly cooled, but actually cold.

Havin thus described my invention,
